spring boot Security 簡(jiǎn)單使用

成都創(chuàng)新互聯(lián)專業(yè)為企業(yè)提供金州網(wǎng)站建設(shè)、金州做網(wǎng)站、金州網(wǎng)站設(shè)計(jì)、金州網(wǎng)站制作等企業(yè)網(wǎng)站建設(shè)、網(wǎng)頁(yè)設(shè)計(jì)與制作、金州企業(yè)網(wǎng)站模板建站服務(wù)，十余年金州做網(wǎng)站經(jīng)驗(yàn)，不只是建網(wǎng)站，更提供有價(jià)值的思路和整體網(wǎng)絡(luò)服務(wù)。

1. 引入依賴

   
   
           org.springframework.boot
           spring-boot-starter-security
   

2. 配置 SecurityConfig@Configuration
   br/>@Configuration
   

           @Autowired
           UserDetailServiceImpl userDetailService;
           @Autowired
           LoginSuccessHandler loginSuccessHandler;
   
           @Override
           protected void configure(AuthenticationManagerBuilder auth) throws Exception {
                   //自定義用戶驗(yàn)證和加密方式
                   auth.userDetailsService(userDetailService).passwordEncoder(new BCryptPasswordEncoder());
           }
   
           @Override
           protected void configure(HttpSecurity http) throws Exception {
                   http.formLogin()                    //  定義當(dāng)需要用戶登錄時(shí)候，轉(zhuǎn)到的登錄頁(yè)面。
           //          .loginPage("/login.html") //自定義登錄頁(yè)面
   //                .loginProcessingUrl("/login") //自定義登錄接口地址
                                   .successHandler(loginSuccessHandler)
                                   .and()
                                   // 定義哪些URL需要被保護(hù)、哪些不需要被保護(hù)
                                   .authorizeRequests().antMatchers("/login").permitAll() //不需要保護(hù)的URL
                                   .anyRequest()               // 任何請(qǐng)求,登錄后可以訪問(wèn)
                                   .authenticated()
                                   .and()
                                   .logout().logoutSuccessUrl("/login").permitAll() // 登出
                                   .and()
                                   .csrf().disable();
           }
   }

3.用戶驗(yàn)證處理

        @Component
        public class UserDetailServiceImpl implements UserDetailsService {
                /**
                 * 用戶校驗(yàn)
                 * @param s
                 * @return
                 * @throws UsernameNotFoundException
                 */
                @Override
                public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
                        Collection collection = new ArrayList<>();//權(quán)限集合
                        String password = new BCryptPasswordEncoder().encode("123456");
                        User user = new User(s,password,collection);

                        return user;
                }

        }

4.登錄成功后處理

@Component
public class LoginSuccessHandler implements AuthenticationSuccessHandler {
        @Override
        public void onAuthenticationSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {

                httpServletResponse.setContentType("application/json;charset=UTF-8");

                httpServletResponse.getWriter().write(authentication.getName());
        }
}

HttpSecurity 類還有很可以使用的函數(shù)
請(qǐng)參考:
